so the car is running perfect no issues or anything, however while driving today in some areas the road was a bit rough bumpy and shortly after i get the car with arrow pointing up workshop... car sits perfect on all 4 coners leveled so now am confused, i did quiet a bit off searching before making this thread, and alot of people got it and turned out to be the acelameter sensor or something like that... i opened the hood and each side has one right on top of struts, held by 2 screws and connector on top....

any advice would be great

if anyone in Tampa area has Star and would be willing to help me and run my system id really appreciate it alot..

I get this message sometimes. You probably have a leak somewhere...

Here is what star says

My car does that from time to time on crappy roads while in sport 2.

or it could be the pump is on its way out, id worry if it happens all the time. Occasionally is fairly common i think.

berti_00

well it never happened before until i drove on that bumpy crappy road.... and 5 minutes later message pops up,

could it be the Acceleration Sensor

This just happened to me recently. I had no leaks but I would get the up arrow error message if I had a lot of weight in the car. It got progressively worse until the error would show up with just me in the car. I had the dealer run the code and they said the compressor was taking too long to come up to pressure. The car was sitting fine, not low, but it just took too long for it to level out. I bought a new compressor off ebay for around $300, replaced it myself, and the problem has been gone since. Dealer wanted around $700. Hope this helps

berti_00

so you think its the compressor pump?

is this the part

That's what I think it is, judging by my experience. I haven't hard any problem with that sensor so I couldn't tell you about that.

Alps

berti, get the codes read first dude

berti_00

okay i did get the codes, my buddy ran it on a computer and it came both left and right Accelerometer Sensor

vioilio

Most likely all you have to do is to disconnect both Accelerometer Sensors and clean the connectors. This did it for me and no more troubles after that!

gaspam

mine did this off an on for about 6 months and then airmatic went out

berti_00

your pump went out??^^^^

okay so am at work now and i parked the car and the rear has dropped while it seems the front has gone up...

what in the hell is going on???

novae500

I have ps arnott strut if you need one.

berti_00

^^^ my bags are fine

it just looks like my car is having a pump going out code 5503 [recovery time during filling of central resivore is to long]
and the other two were the accelometer sensors front left and right.

I have had to deal with this exact same thing three times. The first two times it was the plastic air lines that were leaking at the fittings, and the third time it was the airmatic pump itself that couldn't build enough pressure. I created a thread about it a couple years ago called "Mystery airmatic warning" if you want to search it.

gaspam

no, my airmatic strut/bellow failed eventually and i had to get new one and it was the rear, which arnott doesnt make the cheap ones for so i had to get oem MB one... sucked big time

but from your codes, yours sounds like it could be a pump issue and will prob burnout if its constantly trying to fill up the resevior, but it also could be happening due to a leak somewhere else that is causing the pump resevior to continually deplete itself. if there is a leak somewhere within the airbag assembly then you will be in same boat i was... but if its just the compressor pump then you just have a little and much cheaper diy weekend project

berti_00

yah bags are fine no leaks or anything detected... if It anyone has a pump DIY plz post it here so i could save a few bucks doing it my self...

thanks everyone for the help..

Did exactly this and its been perfect since. the car rode like it was in sport II even when in comfort. To get to the rear sensor take the rear passenger wheel off then remove the fender liner. You'll see the sensor attached to the the body. Disconnect it and blow some compressed air over it. Plug it back in as securely as possible and call it a day. The sensors are located here:

my rear one is good i only got the codes for front right and left
.. thanks for that link i now know were the rear one is..

Start with pump. Check airmatick fuse and pump’s solenoid. When not enough pressure in the system or it’s not building up as fast as system needs it too – codes will be all over the place. If friend has STAR - run pump test.

berti_00

we ran it and gave me this

" code 5503 [recovery time during filling of central resivore is to long] "

were is the airmatic fuse anyways..

MAXHO

Open door all the way and you will se door on a side of the instrument panel. Have to use flat screwdriver to open it. Instructions/fuse location paper should be in there. But it's probably not a fuse - pump would come up at all if fuse bad. Check electrical connector on a pump. It may be corroded (especially if car from north) and pump from working properly. If you need pump check http://http://www.arnottindustries.com/part_MERCEDES-BENZ_Air_Suspension_Parts_yid18_pid127_gid511.htm
they have better price on e-bay, or if your mechanic orders.

berti_00

i doubt its corroded it was a cali car its whole life and now in FL... that link you send me isnt working for me!!!

i am going after this so far as its the cheapest
